Area code 438 at a glance
Where area code 438 comes from
The 438 has overlaid 514 since 2006. The island had run out of numbers and another split was unthinkable on a territory that compact. This overlay is what made ten-digit dialling mandatory in Montreal.
What 438 covers
Exactly the island of Montreal, like 514. Two neighbours on the same floor can hold one 514 and one 438 with no geographic difference at all. Only the date the line opened separates them.

Who answers the phone in 438
It carries Montreal businesses born after 2006: studios, young practices, recent neighbourhood shops and many professional mobile lines opened as teams grew.
The phone day to day in 438
Same time zone and same city as 514, with a younger profile. The 438 shows up heavily on professional mobile lines, so on people answering between appointments. Calls spread further into the evening, especially in consumer services. A business answering on 438 does well to post its hours clearly, otherwise every missed call looks like a closed door.
438 and its neighbours
The 438 is the overlay of 514: same island, same ten-digit dialling. The bridges lead to 450 and 579. To a Montrealer the island's two codes are equivalent; the nuance exists only for those who know their history.
What a 438 number changes for a business
It gives Montreal presence without hunting for a scarce number. For a business opening today or adding a line per department it is the practical choice, and no island customer will read it as second rank.
How to dial a 438 number
Ten-digit dialing is mandatory in the 438 area (overlaid with 514).
Why a 438 number for your business?
A 438 number gives you a local presence in Island of Montreal (overlay). Calls with a local caller ID get picked up more often than an unknown or toll-free number, and your clients recognize a neighbour rather than an out-of-province cold call.
- Picked up more often than a toll-free or out-of-province number.
- Local trust: clients prefer a vendor from their region.
- Remote team: everyone calls from anywhere under the same local number.
- Easy to recall for cards, vehicles and word of mouth.
Who uses a 438 number?
Practices and professional services
Accountants, notaries, consultants: the client calls back a number they recognise, and every exchange stays attached to their file. Missed calls go back out as an automatic text instead of sitting in a mailbox nobody checks.
Shops and workshops
The phone question is short: do you have it, when do you close, what does it cost. The number rings wherever someone can answer, and texting handles the rest without tying up the counter.
Home services
Plumbers, electricians, HVAC: the whole team shares one local number, calls ring whoever's free, nothing slips.
Real estate
A local number doesn't get screened like an out-of-province one. Every call and text stays on the contact record.
Health & clinics
A voice menu routes to scheduling or billing; after hours, urgent calls go through, the rest to voicemail.
Professional services
Accountants, lawyers, advisors: every call is logged, and an AI summary lists action items after the conversation.
Sales
Reps prospect with a local caller ID — picked up more often than an unknown or toll-free number.
Retail & delivery
Order confirmations and delivery windows by SMS from the same local number customers already know.

Porting an existing 438 number
If you already have a 438 number, you do not have to change it. Number portability is a regulated right in Canada: your current provider cannot hold on to a number that belongs to you. The transfer goes to your own telecom account, not ours, which means the number stays in your name once it lands.
In practice you need a recent bill from the current provider and a signed authorisation. Timing depends on the line type, typically a few business days. The line keeps working during the transfer: the switch happens on an agreed date, not into a void.
What a 438 number really costs
There are two bills, and that is deliberate. Relay software comes from us, in Canadian dollars, billed per team with seats included. Telecom comes from your provider, at their published rate, on an account in your name. We do not resell the minute and we take no margin on it.
The consequence is easy to verify: you can open your provider's dashboard and see the real price of every call and every text. That is what changes as volume grows, because a hidden margin on the minute costs more and more the more you call.
Texting from a Canadian number: what to know
Since March 2025, a Canadian number used for business texting requires A2P 10DLC registration or identity verification with the carrier. Many sites still present this as an American matter: it is not, the rule also applies to texting a Canadian customer from a 438 number. The process happens on your own telecom account, with your business details, and like the number it stays yours.
438 or 514: which one?
These codes cover the same territory, down to the street. Technically they are equivalent: same local zone, same rates, same ten-digit dialling. The only real difference is age. Since 438 has been in service since 2006, it reads as the most established, and it is also the hardest to get. The newer overlays offer identical reach with far better availability.
The more useful question is how many numbers you need. A business serving several cities often does better opening one per market than forcing a single number on everyone: the local listing shows the expected code, and the calls still land in the same shared inbox. Because the numbers live on your own telecom account, adding one does not mean renegotiating anything.
One last point, often forgotten: the number you display has to be the one that rings when somebody calls back. A local code on a listing followed by a callback from a placeless number cancels the whole benefit. That is why the outbound call goes out from the same 438 number as the inbound one.
